WAGON DRILL.

Application filed September 10, 1923. Serial No. 661,950.

To all whom it may concern.

Be it known that I, CHARLES O HANSEN, a citizen of the United States, and a resident of Easton, county of Northampton, and State of Pennsylvania, have invented a certain Wagon Drill, of which the following is a specification accompanied by drawings.

This invention relates to rock drills, but more particularly to supporting means mounted on wheels, forrock drills, so that the drill may be conveniently moved from place to place.

In drilling deep holes, such as are required in quarry work, much difficulty has been encountered and time expended in the changing of drill steels. Ordinarily, in drilling deep holes, a steel of short length having a comparatively large bit, is first used to start the hole, and thereafter the length of the steels is increased, with a correspondingdecreasing diameter of bit. In order to remove the steel each time, the operator must shut down the drill, lift the drill or in some way move the drill so that the steel is pulled out I v of the hole, and consequently much time is wasted.

The primary object of the present invention, is to over-come the above difficulties, so that a deep hole may be drilled withoutthe annoyance of constantly changing steels.

Another object of the present invention is to provide a supporting mechanism for a rock drill, so that a comparatively long steel may be used, and the weight of the-drill and associated parts will feed the drill to work without any great operator.

A further object of the invention is to produce a hoisting mechanism for a rock drill,

so that after the maximum depth hole has been drilled, the drill may be easily hoisted, thus enabling the drill steel to be readily removed.

A still further object of the invention is to generally improve upon wagon drills with the view of constructing them more cheaply and sturdily, so that they may stand up under hard usage.

Further objects of the invention will hereinfter appear and the invention is shown in one of its preferred forms in the drawings, in which Figure 1 is a side elevation partly in vertical section of a wagon drill,

Figure 2 is an enlarged detail horizontal effort on the part of the sectional view taken on the line 2-2 of Figure 1, looking in the direction of the arrows,

Figure 3 is an enlarged top plan view of the supports and associated elements,

Figure 4 is a front endelevation of the wagon drill shown in Figure 1,

Figure 5 is a horizontal sectional view taken on the line 55 of Figure 4 looking in the direction of the arrows,

Figure 6 is a perspective view of the centralizer, and

Figure 7 is an enlarged detail horizontal sectional view taken on the line 7 7 of Figure 4.

Referring to the drawings, A designates the frame of a wagon, which is preferably composed of channel beams B and C secured in any suitable manner upon the cross beams D, which are mounted on the axles E and F carrying the wheels G, so that the wagon may be conveniently hauled along the roadway, or across country and in a quarry.

A pair of upright supports H, preferably tubular in form, are secured to the brackets The blocks K are secured to the channel beams B and C, as by the bolts L and nuts 0, and caps K are in this instance bolted down over the trunnions J to the blocks K. Suitable diagonal braces P and cross braces P are provided for the supports H and are connected thereto by the bolts Q, nuts R and washers R. The washers R are formed with curved surfaces which are adapted to fit over the tubular supports H, and flat surfaces against which the bolt heads and braces may bear, and in this manner the braces may be drawn up tightly against the washers. As shown in Figure 2, the diagonal braces and cross braces are secured to the supports by a single bolt on such support, and in this instance the brackets J are formed wit-h flattened portions J 2 against which a cross brace P may bear.

Inorder that the support-s H may be adjusted in an angular position relative to the ground, a pair of legs S carried by the brackets T, are pivoted thereto on the bolts S having washers T on each side of the braces. The brackets T are formed with grooved portions which are adapted to emllU and. the combined weight of the drill and brace the supports H and are secured thereto by thelcross bolts'U' and nuts V. The lower ends of the legs S are pivotally connected by pins X to brackets W, formed with flanges Y adapted to rest upon the upper portions of the channel beams B and C, and a series of holes Z are formed in the channel beams, so that the brackets IV may be adjusted to the desired position by the insertion of bolts 0; in any of the desired holes Z, and in this manner the position of the supports Il may be adjusted relative to the ground.

A cradle 6 having in this instance, curved end portions 0, is located between the supports H, and the curved end portions are slidable thereon. A recess "a is formed in the cradle 6 within which any suitable rock drill c'l is adapted to be clamped by the plates 6, bolts f and nuts g. In order that the drill ti may be raised between the supports. H, suitable hoisting mechanism is provided,- and in this instance, a shaft h is secured to the supportsH by the bolts j, nuts la, and washers 0. The washers'o have curved faces to fit the contour of the supports H, and serve to space the shaft 71. from the supports. A sheave p is'preferably rotatable on the shaft h and a cable 9 is secured at one end to an eye bolt 1" car-- ried by the cradle b and the other end is adapted to be wound on 'a suitable drum 5,

which ismountedon a bracket t, secured to the plate t. A handle a is preferably connected by any suitable gearing to the hoisting drum 8 and provides means for manually winding the cable on the drum for hoisting the rock drill ti.

'A plate o is connected to the lowerends of the supports H by the bolts w, spacing Washers as, and nuts 2, and a reinforcing plate 2 is in this instance riveted to the plate o. In order to guide the drill steel 3 on starting a hole, a suitable centralizer or guide t is provided having recesses 5, which are adapted to be hooked over the plates 1; and2, and a handle 6 enables the centralizer to be attached to or removed from the plate '2), as desired. After the hole has been started, the centralizer may be removed by merely unhooking from the plate 0.

In the operation of the drilling mechanism described, a long steel may "be used,

cradle serve to feed the drill without any great amount of attention from the operator, After the desired hole has been drilled, the drill may be conveniently hoisted and the steel removed. The supports ma be readily adjustedto compensate for changes in the surface of the ground.
